Here's an interesting story from WRAL on the Med Sled, used at WakeMed as an emergency evacuation device. Ten of them are placed around the hospital. They are "rolled up like sleeping bags" and can be quickly deployed to slide patients down stairwells. They were obtained after evacuation drills conducted two years ago found that hospital beds wouldn't fit down stairwells. Read the story. Or learn more about the product on the Med Sled site.
